Quick reply needed about dif/max speed.

Hubs are 4 stud though which is better than the 5 stud Granny ones.

Nice will get it through the iva at least. Will have to send the shafts off to get shortened i guess but still good buy i think. Yeah the 4stud helps as it matches the sierra uprights. Shame about the shaft length but hay for 100quid cant grumble gives me everything i need to get on at least.

[twinturbo]

well the diff will sell on for £60, and the rear calipers,hubs and carrirers for £60+ too.

The rear calipers,hubs and carrirers ect can be used and are the same as the sierra ones i presume? or have i just gone and bought completely the wrong thing? hah

[twinturbo]

Should fit fine, they are slightly different but it should not make any difference.

They will be vented disk which was only ever the case on the 4x4 Cosworth Sierras.

[twinturbo]

Scorpio and Cosworth 4x4 use same rear disks.

Got the original diff i found as well as listed as ford 7.5inch lsd. For £120 but did a offer for £100 that was accepted and its in Poole so only 15min drive. Think that is a ok price or should i have haggled a bit more?
